Abstract
Historically, Industrial Automation and Control Systems (IACS) were largely isolated from conventional digital networks such as enterprise ICT environments. Where connectivity was required, a zoned architecture was adopted, with firewalls and/or demilitarized zones used to protect the core control system components. The adoption and deployment of ‘Internet of Things’ (IoT) technologies is leading to architectural changes to IACS, including greater connectivity to industrial systems. This paper reviews what is meant by Industrial IoT (IIoT) and relationships to concepts such as cyber-physical systems and Industry 4.0. The paper develops a definition of IIoT and analyses related partial IoT taxonomies. It develops an analysis framework for IIoT that can be used to enumerate and characterise IIoT devices when studying system architectures and analysing security threats and vulnerabilities. The paper concludes by identifying some gaps in the literature.
Highlights
The concept of Industrial Automation and Control Systems (IACS) is well established
In undertaking this research our aim was to establish a framework that allows us to analyse the nature of Industrial IoT (IIoT) devices and their uses, which is to be used as part of a vulnerability and threat analysis process for these devices
We are able to provide our own working definition of IIoT. It has the same structure as the simple conception we started out with: IIoT is defined by appeal to the kinds of technologies which compose it, as well as by appeal to the distinctive uses to which those technologies are put, but builds in more details that the simple conception: Industrial Internet of Things: A system comprising networked smart objects, cyber-physical assets, associated generic information technologies and optional cloud or edge computing platforms, which enable real-time, intelligent, and autonomous access, collection, analysis, communications, and exchange of process, product and/or service information, within the industrial environment, so as to optimise overall production value
Summary
The concept of Industrial Automation and Control Systems (IACS) is well established These systems, often referred to as Operational Technology (OT), are employed in diverse industries including manufacturing, transportation and utilities, and are sometimes referred to as cyber-physical systems (CPS). The aims of this paper are to improve on existing definitions of Industrial IoT (IIoT) and to propose a framework for IIoT components as a basis for analysing the use and deployment of IoT technologies in industrial settings. In undertaking this research our aim was to establish a framework that allows us to analyse the nature of IIoT devices and their uses, which is to be used as part of a vulnerability and threat analysis process for these devices.
